INSTALLATION GUIDELINES

Connecting the GND (GROUND) screw terminal

If you connect a low-level audio input source (turntable) to the PHONO, please connect your turntable’s ground wire (usually black or green) to the amplifier’s GND terminal, to avoid a low-frequency hum. You can also use this screw to ground any other system connection.

Input connections

The PT110/PT210 accept a broad range of input sources, including Microphones (up to two simultaneously) Compact Disc (CD) player Cassette, Reel-to-Reel, or another tape player Radio Tuner Magnetic Cartridge Turntable

Connecting microphones

The MIC 1 and MIC 2 jacks permit you to connect two microphones with a 6.35mm plug.

Connecting a CD tape player, or tuner

In this situation, set the PHONO and AUX/CD SELECTOR switch to the AUX/CD

Connecting a turntable

In this situation, set the PHONO and AUX/CD SELECTOR switch to the PHONO.

Speaker connections

One or more speakers (4, 8, or 16-Ohm) speakers can be connected to the amplifier with or without transformers. However, before you connect any speaker to the amplifier, the total speaker impedance must be calculated to avoid damage to the amplifier. A total speaker impedance greater than 16 Ohms or less than 4 Ohms can cause this damage to occur.

To begin with, to ensure equal volume from each speaker, all connected speakers should have the same impedance.

A proper total impedance with the 4 to 16 Ohms range can be achieved by combining series and parallel speaker connections. Please see the diagrams which follow the same impedance.

Finally, always use the shortest length of speaker wire possible of proper gauge. Usually, 18-gauge wire is adequate for lengths under 25 feet, while 16-gauge is used for greater lengths.

System 1: Single speaker system

1. Connect the speaker (-) terminal to the amplifier COMMON terminal
2. Depending on the speaker being used, connect the speaker (+) terminal to the amplifier’s 4-Ohm, 8-Ohm, or 16-Ohm amplifier terminal.

System 2:Two (or more) speakers in series

1. Connect the LEFT SPEAKER (-) to the amplifier COMMON terminal.
2. Connect the LEFT SPEAKER (+) to the RIGHT SPEAKER (-).
3. Connect the RIGHT SPEAKER (+) to the amplifier’s 4-Ohm, 8-Ohm, or 16-Ohm terminal, depending on the TOTAL IMPEDANCE of the two speakers.

If each speaker has an impedance of 8 Ohms, the total speaker impedance in this series configuration is 16 Ohms.

NOTE: ADDITIONAL SPEAKERS MAY BE INCLUDED IN SERIES, BUT IT IS NECESSARY TO CALCULATE TOTAL IMPEDANCE AND CONNECT THE SPEAKER CIRCUIT TO A TERMINAL OF APPROPRIATE IMPEDANCE. FOR EXAMPLE, IF THREE SPEAKERS OF 4-OHM ARE USED, THE TOTAL IMPEDANCE IS 12 OHMS, YOU SHOULD CONNECT TO THE 16-OHM TERMINAL.

System 3:Two (or more) speakers in parallel

1. Connect the LEFT SPEAKER (-) to the RIGHT SPEAKER (-).
2. Connect BOTH the LEFT SPEAKER (-) and the RIGHT SPEAKER (-) to the amplifier COMMON terminal.
3. Connect the LEFT SPEAKER (+) to the RIGHT SPEAKER (+).
4. Connect BOTH the LEFT SPEAKER (+) and RIGHT SPEAKER (+) to the amplifier 4-Ohm, 8-Ohm, or 16-Ohm terminal, depending on the TOTAL IMPEDANCE of the two speakers. If each speaker has an impedance of 8-Ohm, the total speaker impedance in this parallel configuration is 4 Ohms.

System 4:Four speakers in series/parallel combination

1. Group the four speakers into two pairs.
2. Connect each pair of speakers in SERIES (see system 2 above). If you connect 8-ohm speakers, the total impedance of each pair is 16 ohms.
3. Connect the two pairs of speakers in PARALLEL, If you connect 8-ohm speakers, the total impedance of both pairs is 8 ohms. Note: If each of the four speakers is 8 ohms, the total speaker impedance of the combined series/parallel connection described above is also 8 ohms. Likewise, the total speaker impedance is 4 or 16 ohms, if the speakers are 4 or 16 ohms respectively.
4. Connect the speakers’ (-) terminals to the amplifier’s COMMON terminal.
5. Connect the speakers’ (+) terminals to the amplifier’s 4-Ohm, 8-Ohm, or 16-Ohm terminal, depending on the TOTAL IMPEDANCE of the FOUR SPEAKERS

See the chart below for some sample system suggestions:

COMBINATION OF TWO SERIES PAIRS IN PARALLEL

SERIES/PARALLEL VARIATIONS

Although the description above is for combining TWO SERIES PAIRS in a PARALLEL hook-up, you may also select to combine a SERIES PAIR and a PARALLEL PAIR in a PARALLEL hook-up. Simply be sure you have properly calculated the total impedance, and connect the (+) speaker circuit wire to the proper amp terminal. For example, if you use a SERIES PAIR of 8-Ohms speakers (the total impedance is 16 ohms) and a PARALLEL PAIR of 8-Ohms speakers (the total impedance is 4 ohms) in a PARALLEL hook-up, the TOTAL IMPEDANCE of this system is 3.2 OHMS, so you should connect the (+) speaker circuit wire to the 4- OHM terminal.

See the chart below for some sample system suggestions:

COMBINATION OF ONE SERIES PAIR AND ONE PARALLEL PAIR IN PARALLEL

This example shows the first three systems in the chart. In this case, the 4-Ohm terminal is used your system impedance may be varied depending on the impedances of the individual speakers, and may require hooking up to the 8 or 16 Ohms terminal.

System 5: Connecting speakers with transformers

1. Locate the input taps on your transformer. These taps are on the side of the transformer and are rated in watts, 10, 5, 2.5, 1.25, or 0.62. Usually, each speaker in a system uses the same wattage tap. Connect the selected tap to the amplifier 70V RMS terminal. If you wish a particular speaker to have a higher volume level, connect the wire from 70V RMS to a
   higher wattage tap on the transformer.
2. Connect the transformer’s COMMON tap on the primary side to the amplifier COMMON terminal.
3. Connect the speaker’s (+) terminals to the transformer’s secondary tap that matches the speaker’s TOTAL IMPEDANCE. Located on the opposite side of the transformer, these secondary taps are outputs and are rated in Ohms 4, 8, or 16.
4. Connect the speaker’s (-) terminals to the transformer’s COMMON tap on the secondary side.

NOTE: Before connecting the speakers, please be sure the total wattage of the primary tap you use does not exceed the amplifier’s maximum power rating, PT110 20W and PT210 40W.

ALSO: Avoid, where possible, multiple connections to the 70V RMS and COMMON terminals.

Using headphones

To listen privately, or to monitor sound sources, connect a pair of low-impedance stereo headphones (not supplied) with a 6.35mm plug into the PHONES jack on the amplifier front panel.

Please listen safely. Follow these recommendations: Do not listen at extremely high volume levels. Extended, High-volume listening can lead to permanent hearing loss.

Always start with the volume control set to a LOW level BEFORE you put the headphones on. Then gradually increase the volume as necessary.

Connecting to standard AC power

After making all other connections, set the POWER switch to the OFF position. Then connect the power cord to a standard AC outlet. Connecting to 4A/12V DC power (PT110) You can power the amplifier from your vehicle’s 12-volt
battery. Connect the supplied DC power cable’s barrel plug to the DC 12V IN jack on the amplifier, and then connect the cable’s other end to the 12-volt accessory socket on the vehicle, such as the cigarette-lighter socket.

CAUTIONS:

PLEASE UNPLUG THE AC POWER CORD BEFORE CONNECTING THE DC POWER CABLE FOR THIS 12V POWER USAGE, AND DISCONNECT THE DC POWER CABLE BEFORE PLUGING IN THE AC POWER CORD FOR AC POWER USAGE. THE VEHICLE USED FOR THIS POWER SOURCE MUST HAVE A NEGATIVE GROUND ELECTRICAL SYSTEM. IF YOU ARE NOT SURE OF IT, PLEASE CHECK WITH YOUR VEHICLE’S DEALER.

Turning the amplifier on

1. Turn on the audio input source equipment which is connected to the amplifier INPUT jack.
2. Set all volume levels (MASTER, MIC 1, MIC 2, and PHONO/AUX) to their minimum level settings.
3. Press the power switch to turn the amplifier on.
4. Adjust the controls of MIC 1, MIC 2, and PHONO/AUX to the achieve desired volume and balance.

Using the LED power meter

The meter LED position indicates the amplifier output power.

Using the MASTER volume control

The MASTER volume control increases or decreases output level gain. To obtain the best performance with the least distortion, be sure to adjust the output level so that the LED meter does not continually exceed the right extreme of the meter’s range.

CAUTION: Setting the output level too high can overdrive the amplifier, causing permanent damage.

Using the MIX BUS jack

You can connect another PT110/PT210 to this jack to double the size of your PA system. This lets you use up to four microphones and two turntables (or two auxiliaries) sound sources.

Use a shield cable with phono plugs at each end, and connect the cable between the MIX BUS jacks on the back of two amplifiers. For the best results, do not use a cable longer than 6 feet.
